INTRODUCTION: Ultrasonography is extremely well suited to study of scrotum and its contents. Ultrasound is simple to perform, quick, non-invasive, low cost effective, easily reproducible, widely available and does not involve irradiation of gonads.It is very helpful in differentiating intratesticular and extratesticular pathologies. Ultrasound is the modality to differentiate solid from cystic lesions of testes and with the introduction of color Doppler, it becomes easiear to assess the viability of testis in cases of torsion and guiding the treatment accordingly. USG is helpful in differentiating torsion/ischaemia of testis from the acute inammatory pathologies. Role of other Modalities: CT and MRI have dominated imaging of other regions of the body, they have certain restrictions in evaluation of scrotal diseases. Computed Tomography delivers radiation to gonads, On the contrary, MRI imaging is expensive and not readily obtainable. Radionuclide scan helps in equivocal presentations to assess vascularity within the testis in setting of torsion but its readily availability and cost is the main set back. AIM: To assess the role of high frequency gray scale and color doppler ultrasonography in evaluation of epididymorchitis. MATERIAL & METHODS: SAMPLE: 50 cases of scrotal pathology were taken using High-frequency real time gray scale ultrasonography and Color Doppler . Patients were referred to our department for scrotal ultrasonography and Doppler study by department of Urology and department of Surgery of SRMS IMS Bareilly. RESULTS: In the present study total evaluated cases of epididymoorchitis were 15,among them 11 cases were acute and 4 cases were of chronic epididymoorchitis.. Majority of cases were having unilateral involvement with 1 case of B/L involvement. USG gray scale found heterogenous echogenicity or reduced echogenicity in acute EPO while the echogenicity was reduced with calcication in chronic EPO. .Doppler study found increased vascularity in majority of cases of acute EPO with reactive hydrocele while vascularity was either normal or increased in chronic EPO without any reactive hydrocele. CONCLUSION: High-frequency gray scale USG helps in clear evaluation of anatomical structural alterations associated with acute scrotal inammatory diseases, and color Doppler USG is highly sensitive in diagnosing acute scrotal pathology. In addition, Color Doppler USG accurately differentiates between testicular ischemia and torsion from acute inammatory diseases in acute painful scrotal conditions.

Acute Scrotal Pain

Background: Traditionally acute scrotal pain is evaluated by gray scale ultrasound, which dissipated only the morphological changes of the lesion. But pattern of vascularity either normal, increased or absent of affected structure help to definitive diagnosis of the lesion and help to proceed the type of management either medical therapy or surgical treatment.Objectives: To determine the relative importance of color Doppler in the evaluation of acute scrotal pain by ultrasound.Methods: From June 2013 to June 2017 a total 150 patients with acute scrotal pain were selected. A thorough history taking and physical examination were done. Then patient were scanned with gray scale ultrasound followed by color Doppler study. Color Doppler diagnosis is compared with gray scale diagnosis.Results: In gray scale ultrasonography among the 150 cases, 54% were diagnosed as epididymitis, 16.66% were epididymo-orchitis and 16% patient diagnosed as normal. But in combined gray scale and colour Doppler study 58% were diagnosed as epididymitis, 22% were epididymo-orchitis and 6% of patient diagnosed as normal. In gray scale 10% patient were diagnosed as normal but become epididymitis and epididymo-orchitis in colour Doppler. Four percent were diagnosed as epididymitis in gay scale but became epididymo-orchitis in colour Doppler. Four percent patient was diagnosed as epididymitis orchitis but became testicular torsion in Doppler study. Total 14.66% of gray scale diagnosis became another diagnosis in the Doppler study.Conclusion: Combined gray scale and color Doppler study is superior than gray scale ultrasound in differentiating various cause of acute scrotal pain.Bang Med J (Khulna) 2017; 50 : 26-30

ABSTRACT: BACKGROUND: A common surgical emergency is acute appendicitis. Various diagnostic tools are available to diagnosis acute appendicitis. Radiological investigations play an important role in making accurate and early diagnosis and thus preventing morbidity associated with the disease. OBJECTIVE: To determine the diagnostic accuracy of gray scale ultrasonography versus color Doppler in suspected cases of acute appendicitis. MATERIALS AND METHODS: The study was carried in the department of Radiology of Mayo Hospital, Lahore. A total of 75 patients were enrolled of age 18-40 years, both genders who were suspected cases of acute appendicitis. All patients underwent baseline investigations along with gray scale ultrasonography and color Doppler. All patients were subjected to surgery to confirm the diagnosis and findings were subjected to statistical analysis. RESULTS: The mean age of the patients was 23.25 ±10.55 and mean transverse diameter of appendix was 8.37 ±3.39. There were 62.7% males and 37.3%females. Findings of gray scale ultrasonography and color Doppler were then correlated with surgical findings to calculate the diagnostic accuracy of these modalities. The results revealed that gray scale ultrasonography sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 92.7%, 94.32%, 95%, 91.4% and 93.3% respectively, whereas color Doppler had sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 97.7%, 93.9%, 95.3%, 97% and 96% respectively. Diagnostic accuracy of both modalities together was 98.6%. CONCLUSION: Color Doppler has better diagnostic accuracy than gray scale ultrasonography for diagnosis of acute appendicitis and the combination of both modalities yields diagnostic accuracy that is similar to gold standard.
